NASA's TRMM satellite sees a well-organized, major Typhoon SongdaTyphoon Songda was east of the Philippines when the Tropical Rainfall Measuring Mission (TRMM) satellite had an early evening view on May 25, 2011 at 0903 UTC (05:03 EDT) and saw good organization within the storm and heavy rainfall. Songda has intensified into a major typhoon as it tracks parallel to the east coast of the northern Philippines, spawning warnings.http://phys.org/news225561732.html

EarthMon, 13 Dec 2010 12:10:02 ESTnews211462643Threshold sea surface temperature for hurricanes and tropical thunderstorms is risingScientists have long known that atmospheric convection in the form of hurricanes and tropical ocean thunderstorms tends to occur when sea surface temperature rises above a threshold. The critical question is, how do rising ocean temperatures with global warming affect this threshold? If the threshold does not rise, it could mean more frequent hurricanes.http://phys.org/news208430569.html
